ABSTRACT:
A hanger and stinger assembly includes an expandable joint therebetween for the stinger to be telescoped with the hanger between extended and collapsed positions. An actuating spool for use in conjunction with a wireline tool mechanism is provided for hydraulically actuating the slips on the hanger and a releasable catch is connected between the stinger and a tubular receptacle mounted on the hanger to normally limit upward movement of the stinger to its extended position. A latch at the upper end of the stinger is utilized to hold the catch in a release position enabling the stinger to be withdrawn from the receptacle by a straight pull and a locking mechanism normally positions the latch to keep from holding the catch in its release position and the locking mechanism is hydraulically actuated.
